Portrait of Vincent Ruan
About

Engineer, founder, and builder of the parts no one owns yet.

I’m Vincent — an engineer and founder based in New York with 8+ years shipping distributed systems, developer infrastructure, and production AI. I’ve done that at AWS and Microsoft, and as co-founder and CTO of two startups.

What I keep coming back to is the ambiguous, high-ownership problem — the piece no one has figured out yet. I like carrying something from an empty repo all the way to a service running in production, and owning every layer in between: product, infrastructure, and the hard correctness details.

These days I’m spending that on my own things — building products end to end, from DeFi protocols and Solana trading infrastructure to multi-agent AI for financial research, and a handful of businesses I run myself.

Things I’ve built

A few of the products and systems I’ve shipped — some live for anyone to use, some running quietly in production.
